Abstract: PURPOSE: A method for automatically and stably allocating multicast addresses of an IPv6(Internet Protocol version 6)-based node in a network layer is provided to combine a lower 64-bit interface ID of link-local unicast addresses and side-local unicast addresses set in interfaces of every node with information acquired from a router, so as to automatically generate link-local multicast addresses and side-local multicast addresses in a host. CONSTITUTION: Each IPv6 node checks whether unicast addresses are set in interfaces(S10). If so, a packet delivery range of the unicast addresses is checked, if global, to return to the step S10 without additional processing(S20). If the packet delivery range indicates side-local, a 16-bit subnet ID and a 64-bit interface ID are extracted from the unicast addresses(S30,S40). If the packet delivery range indicates link-local, only the 64-bit interface ID is extracted from the unicast addresses(S30). Whether to provide a security function for the 64-bit interface ID extracted from the unicast addresses is checked(S50). If the security function is decided to be provided, the 64-bit interface ID is enciphered(S60). If the security function is decided not to be provided, and after enciphering the 64-bit interface ID, a 32-bit group ID is generated(S70). And obtained information is combined to generate link-local multicast addresses and side-local multicast addresses and store generated addresses according to interfaces on each node(S80), then the step S80 is returned.

Abstract: PURPOSE: An IPv6(Internet Protocol version 6)-IPv4 NAT-PT(Network Address Translation-Protocol Translation) method using an automatic port translation and a recording medium therefor are provided to prevent the waste of an idle time in which hosts of an IPv6 network wait until another address is released and enhance the utilization of an IPv4 address pool by automatically translating an address translation method into a port translation method when a use rate of an address pool to be translated is greater than a specific threshold value. CONSTITUTION: If IPv6 packets are transmitted from IPv6 hosts, an IPv6-IPv4 address translation device receives the IPv6 packets and compares a use rate of an IPv4 address pool with a predetermined threshold value for judging whether the use rate of the address pool is less than the predetermined threshold value(S11). If the use rate of the address pool is same to or greater than the predetermined threshold value, the IPv6-IPv4 address translation device automatically translates an address translation method into a port translation method for translating the IPv6 packets into IPv4 packets and transmitting the IPv4 packets(S15).

Abstract: PURPOSE: A method for assigning a multicast address using a link local address and an apparatus therefor are provided to assign the multicast address which does not generate a collision with an other multicast address using a link local IPv4(Internet Protocol version 4) address without a separate multicast address assignment server. CONSTITUTION: A host selects lower 16 bits, combines the selected lower 16 bits with prefix information, and generates one link local host IP address without a DHCP(Dynamic Host Configuration Protocol) server(S101). The host checks whether the collision of the generated link local host IP address is generated in a link through an ARP(Address Resolution Protocol)(S102). If the collision of the generated link local host IP address is not generated, the host assigns the corresponding address as its link local host address(S105). The host generates prefix information for a plurality of multicast addresses usable in a predetermined local area corresponding to prefix information of the assigned address(S106). The host copies the lower 16 bits of the assigned link local host address through the collision test(S107). The host combines the copied lower 16 bits of the link local host address with a plurality of generated prefix information, and assigns 3 multicast addresses in the link(S108).

Abstract: PURPOSE: A dynamic frame selecting method in video on demand is provided to minimize deterioration in service quality and to variably adjust traffic while dynamically controlling service quality in VCR performance. CONSTITUTION: A current user session is converted into an interactive service mode according to a user's request for a video cassette recorder function(206). An available band width capacity is calculated using the converted service situation and the entire band width capacity to check the traffic state(207).

A corresponding frame select parameter is decided and a dynamic frame for video selected by the decided select parameter is chosen(209). The amount of traffic generated according to the decided frame select parameter and service quality are variably controlled to transmit the chosen frame(210).

Abstract: 본 발명은 무선 비동기식 전송 모드(ATM)망을 위한 매체 접근 제어 프로토콜에서의 동적 대역 할당 방법에 관한 것이다. 실시간 전송을 요구하는 가변 비트율(VBR)의 트래픽에 대하여 슬롯 할당에 따른 사용율을 극대화하기 위해서는 이동국에서의 트래픽 발생 상황에 대한 정확한 정보를 기지국으로 전송하여야 한다. 그러나 이동국에서의 이러한 트래픽 발생 상황 정보를 대역 내 제어 신호 방식으로 전송하는 경우 실제 전송되는 셀에 과다한 오버헤드가 발생하고, 대역 외 제어 방식으로 트래픽 상황 정보를 전송하는 경우에는 대역 외 경쟁 슬롯의 이용으로 인한 경쟁에 따른 지연시간으로 실시간 정보의 교환이 불가능해지는 문제점이 있다. 이러한 문제점을 해결하기 위하여 본 발명에서는 트래픽 발생 상황 정보의 직접적인 교환 없이 이동국에 할당된 슬롯 중 마지막 슬롯에 표시된 최소 요구 슬롯 수의 존재 여부에 따라 해당 이동국이 다음 프레임에서 필요한 슬롯의 수를 계산하여 동적 대역 할당을 수행하므로써, 추가적인 정보 전송을 위해 요구되는 대역 내 및 대역 외의 오버헤드를 줄이고 처리의 복잡도를 최소화 할 수 있는 무선 비동기식 전송 모드망을 위한 매체 접근 제어 프로토콜에서의 동적 대역 할당 방법이 제시된다.

Abstract: PURPOSE: An IPv4 communication method under IPv6 wireless LAN environment is provided to give all services by using an IPv6 address, and to dynamically receive a public IPv4 address if an IPv4 terminal is communicated, thereby carrying out communication with the IPv4 terminal. CONSTITUTION: An initial IPv6 terminal prepares for a process(210). The initial IPv6 terminal interprets an IP for a domain name at the request of an application program(220). The initial IPv6 terminal decides whether a destination address for the requested domain name is a public IPv4 address(230). If so, the initial IPv6 terminal is dynamically assigned with the public IPv4 address for IPv4 communication(240). The initial IPv6 terminal returns the address when the public IPv4 address expires(250).
